The sodium-potassium pump can transport
WebMay 17, 2024 · Active transport is a highly demanding metabolic process; some cells can use up to 50% of their energy on active transport alone. A key example of an active transporter is the sodium-potassium (Na/KATP-ase) pump. This exports three sodium ions in return for two potassium ions. This is key to maintaining the resting membrane … WebSome examples of pumps for active transport are Na +– K + ATPase, which carries sodium and potassium ions, and H +– K + ATPase, which carries hydrogen and potassium ions. Both of these are antiporter carrier proteins. Two other carrier proteins are Ca 2+ ATPase and H + ATPase, which carry only calcium and only hydrogen ions, respectively.

Let's say that the concentration of glucose is higher inside … Webreduced potassium permeability accounts for a steady state in which the high intracellular potassium concentration is “protectedq even though there is a large outward directed driving force, (V m−E K), for potassium ions. In [14] a simpler model was presented that involved only sodium and potassium. That model employed a Michaelis–
WebApr 28, 2024 · Examples of Transport Proteins The Sodium-Potassium Pump. The most famous example of a primary active transport protein is the sodium-potassium pump. It is this pump that creates the ion gradient … WebUnder the influence of palytoxin, yeast cells that express the mammalian sodium pump exchange extracellular Na+ ions for intracellular K+ ions with a stoichiometry of approximately 1:1. Both fluxes can be inhibited by ouabain. K+ efflux can also be observed when extracellular Na+ is replaced by Li+, Cs+, or NH4+.
WebDec 24, 2024 · Active transport is responsible for cells containing relatively high concentrations of potassium ions but low concentrations of sodium ions. The mechanism responsible for this is the sodium-potassium pump, which moves these two ions in opposite directions across the plasma membrane. WebApr 9, 2024 · The sodium-potassium pump moves K + into the cell while moving Na + out at the same time, at a ratio of three Na + for every two K + ions moved in. The Na + -K + ATPase exists in two forms, depending on its orientation to the interior or exterior of the cell and its affinity for either sodium or potassium ions.
